[Fire TV Android Development] rbox:
It's finally here! Recovery for the Fire TV 2. This is based off of TWRP and the way versions will work is I will increment the last digit in the version as I make updates. So 3.0.0-1 is my first release based off of 3.0.0. The downloads will be numbered starting at v1, and at the bottom of the post it will explain what is contained within each version.

​

As usual, this WILL void your warranty and I am NOT responsible for anything you do with this. Installing it properly won't brick your Fire TV, but doing stupid things with it might.

Installing this requires root. If you are not rooted, please see my FireTV 2 Recovery Installer page.

Installation

You can copy the files to /sdcard, a USB storage device, or an sdcard. I will be using /sdcard in the instructions, but you can replace it with /storage/usbotg for USB or /storage/sdcard1 for an sdcard.

Copy the zip file to your destination.

Connect adb

adb connect IPADDRESS

Open an adb shell

adb shell

Run the zip file (replace vX with the actual version you downloaded). This will automatically run su, so make sure to accept the prompt if necessary.

sh /sdcard/firetv2_recovery_vX.zip

Reboot

Upgrade

You may repeat this to upgrade to a newer version, or you can install an updated pre-rooted rom, as I will be uploading new versions of those with every version of recovery.

Notes

This includes bootmenu. For everyone that loved the old FireTV 1 bootmenu with Comic Sans, I'm sorry to disappoint you, but the Comic Sans is gone. When the FireTV boots, it will present you with the bootmenu where you can leave it alone and it will boot normally or you can select recovery and it will boot in to recovery. You do need a USB keyboard to interact with the bootmenu. To force it to boot in to Recovery, you can create a file /cache/bootmenu_recovery.

DHCP for Ethernet is enabled, and if there is enough demand I may add in wifi at some point. The IP address should show up in the top left corner.

USB storage, USB keyboard/mice, and sdcards should all work. Hotplugging works, so you should be able to plug and unplug devices as needed.

You can use a USB keyboard, mouse, or the mouse emulator to interact with it. To use a keyboard, you can use the arrow keys to move the cursor and the enter key to select buttons. Sliders don't require sliding, so you can just hit enter/click on them. To use the mouse emulator, use adb shell and then run the program mouse and follow the instructions.

ROMs

Recovery must be included in all ROMs. If you want to develop a ROM, please contact me about including recovery in it.

Kernels

The bootloader is locked and you cannot flash kernels. If you do attempt to flash a kernel, you will brick it.

Installing zips

You can push zips to /sdcard, put it on a USB storage, put it on an sdcard, or use adb sideload. Do note you need adb version 1.0.32 to use adb sideload.

Stuck in a loop?

If you cannot boot normally and keep going back to the bootmenu, wipe Cache from Wipe -> Advanced Wipe.

If that doesn't work, ensure Cache is not mounted from in the 'Mount' menu and run this from an adb shell:

mke2fs /dev/block/platform/mtk-msdc.0/by-name/cache

Source Code

You can find the source code here:

https://github.com/androidrbox/android_bootable_recovery

WARNINGS

It is extremely important you never reboot after a failure. This will most likely lead to a brick. If recovery is hung, you can use adb shell to run

killall recovery

to restart it

It is also extremely important to never reboot after wiping /system.

If you wind up bricking, you must use the Unbrick Image to unbrick.

Finally, thanks to everyone who has donated to me and those that helped to get me my FireTV 2.
